As I already mentioned I asked not to add any custom bindings to support
multiple cluster. But this version removed APMU node from DT completely
which is not correct.

Also you removed multi cluster support to avoid CCI and MCPM reuse. I
think you may have to rework these completely when adding multi-cluster
support. I strongly recommend to reuse the CCI and MPCM code from first
instead of reworking again, but I leave it SH platform maintainer to
decide.
